Based on vintage sports shirts from the '50s, this dog features two different shades of washed-down indigo. Fully reversible, slightly thicker than our other longsleeves, and not to brag, but one side even has a chest pocket. Our blend of cotton and tencel is lightweight but durable, and as always, absurdly soft. Derrick, who runs a hat company when he's not busy being offensively handsome, is 6'0 and wears a Medium.
